Transferring Accounts - Out of IP Addresses Problem

I need to transfer about 100 accounts owned by about 20 resellers from one server to another. Copying them individually, is out of the question - obviously.

Both servers are on the latest CURRENT trees - so whm/cpanel 11.

Now, it copies the first account fine, second file, and the rest fails, because of the error:
"Account Creation Status: failed (Unable to find an ip address"
The server has 3 IPs, the main shared IP and 2 for nameservers.

I would suggest, if no one provides an acceptable solution, you find some person/company experienced at this sort of thing.

Transferring Reseller accounts is lot more tricky than if just Hosting accounts.

Along with the current problems mentioned, if not done right then after the transfers are completed you will have to edit every DNS record so each Reseller has correct Ownership of 'their' Clients and each of 'their' Clients are using the correct Nameservers -- presuming each Reseller has 2 Dedicated IPs and Personal Nameservers.
